re: imported roads not connecting to existing osm roads. Yes, we know about that... and we decided that is was better to preserve all the work that the osm mappers have done, as the alternative would have been to wipe out the existing OSM road network.
Because of things like extra tags and relations which already exist in the OSM database (like Bus networks, cycle networks) and long distance networks, we didn't want to interfer with that. Fortunatly however, the roads are avaialable as an overlay from the canvec2osm set that i have, so then anyone can load it, and use it to help connect the edges. One of the things, (and perhaps its a good reason) that for the canvec import, im going the route of having the script available and having it that people can manually import each .osm feature file at a time, and then at the same time after that, be going in there and fixing up the roads. The "wipe-and-replace" process, did happen in The Netherlands for the AND import, however, it wipes out So much work that mappers have done, that it just didn't make sence. Also, the Tiger import happened back before alot of other mappers were mapping and filling it in. So the script for the "automatch" seems to be the best solution, as it preserves the existing data, and then only adds in the roads that don't interfere with existing data. What we also do is keep track, and have a backup of the full conversion file, so then users can use it, as an example. So those actual mappers who drew in the roads in the 1st place, have the option of removing their own work, ... rather than making that decision for them. In short, the decision to preserve the integrity of the OSM data, was placed at a higher value than that of the Geobase Import Data. Hope that answers the question (im sure others might also answer it, as it's a contentious issue that we dealt with before christmas) Cheers, Sam Vekemans Across Canada Trails _______________________________________________ Talk-ca mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ca
